Created attachment 708204 [details]
y2log for only the bootloader session

YaST/bootloader configured, with the options shown in the screenshot
Bootloader_code_tab.jpg.

There is nowhere set or mentioned (displayed) at which disk the bootloader will
be stored.  From the documentation [1] and help [2] I understood that the
bootloader would be stored at 1st disk (sda), but according the logs the
bootloaders is stored at sdb.  Why?   

On the other hand it's something I wanted (bootloader at disk sdb) so I can
test the bootloader.  After booting the system and selecting the 2nd disk (sdb)
there is no bootprompt at all :(

Two questions:
1) Why is the bootloader saved at sdb (2nd disk) and not to the 1st?
2) The system does not boot from the saved bootloader at sdb, why?
